A parameter design of a pinhole array is one of the most important keys to design an integral imaging (II) display using pinhole array. The relationship between the thickness of the pinhole array and the viewing angle of the II display is studied, and the maximal value of the thickness is also obtained. When the thickness of the pinhole array is greater than the maximal value, the viewing angle of the II display is decreased with increasing the thickness of the pinhole array. A prototype of the II display using pinhole array is developed, and the experimental results agree well with the theory.
